Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A variable biometric information-based authentication system comprising: a mobile terminal configured to generate information regarding an ID that intends to access a facility or information requiring an access authority, and to collect variable biometric information, such that information regarding the 1 D and the variable biometric information are stored all together; and a variable biometric information management server configured to, when the mobile terminal requests a login command regarding the ID, verify validity of the login command regarding the ID based on the variable biometric information, wherein the variable biometric information management server is configured to determine whether a specific ID is an ID of a first security level or an ID of a second security level based on the information regarding the ID, the ID of the first security level allowing the validity of the login command regarding the ID to be verified based on one type of variable biometric information, the ID of the second security level allowing the validity of the login command regarding the ID to be verified based on a combination of two or more types of variable biometric information or a complex arithmetic relation, and wherein, when the specific ID is the ID of the first security level, the mobile terminal is configured to collect the variable biometric information, and to transmit only information regarding a figure or a form of a graph indicating a variation in a specific section, without transmitting a real value of the collected variable biometric information to the variable biometric information management server.
A biometric authentication system uses variable biometric data to verify access requests for facilities or information. The system includes a mobile terminal and a management server. The mobile terminal collects biometric data, such as behavioral or physiological characteristics, and associates it with a user's ID. The server determines the security level of the ID, which dictates the authentication method. For lower-security IDs, the system verifies access using a single type of biometric data, while higher-security IDs require multiple biometric types or complex calculations. The mobile terminal transmits only graphical representations of biometric variations, not raw data, enhancing security by preventing direct exposure of sensitive biometric values. This approach ensures flexible authentication based on security requirements while protecting user privacy.
2. The variable biometric information-based authentication system of claim 1 , wherein the variable biometric information management server is configured to: when the information regarding the ID matched with the variable biometric information and stored, and the variable biometric information including only the information regarding the figure or the form of the graph are received, store the received information regarding the ID and the variable biometric information; when a login command regarding the specific ID is requested, receive variable biometric information for verifying validity of the login command from the mobile terminal; compare the received variable biometric information and the figure or the form of the graph included in the stored variable biometric information including only the information regarding the figure or the form of the graph on a real time basis, and to verify the validity of the login command.
This invention relates to a biometric authentication system that uses variable biometric information, such as dynamic patterns or gestures, for secure user verification. The system addresses the limitations of static biometric authentication methods by leveraging dynamic, user-specific inputs that are difficult to replicate. The system includes a variable biometric information management server that processes and stores biometric data linked to user IDs. When a user registers, the server receives and stores an ID along with variable biometric information, which consists solely of graphical or form-based data, such as a signature, gesture, or dynamic pattern. During login, the server receives a new biometric input from a mobile terminal and compares it in real-time to the stored graphical data to verify the user's identity. This comparison ensures that the login attempt is valid, enhancing security by detecting unauthorized access attempts. The system improves upon traditional authentication methods by using dynamic, non-static biometric data, reducing the risk of spoofing or replay attacks. The real-time comparison further strengthens security by ensuring that the biometric input matches the registered pattern, preventing unauthorized access. This approach is particularly useful in mobile environments where secure, user-friendly authentication is required.
3. The variable biometric information-based authentication system of claim 2 , wherein the variable biometric information management server is configured to accumulate and store the variable biometric information including only the figure or the form of the graph according to the information regarding the ID, and, when the mobile terminal requests the variable biometric information stored for the specific ID to be discarded, the variable biometric information management server is configured to discard the variable biometric information stored for the specific ID, and to accumulate and store the variable biometric information transmitted with the information regarding the specific ID after the stored variable biometric information is discarded, according to the information regarding the ID.
A biometric authentication system uses variable biometric information, such as dynamic patterns or behaviors, to verify user identity. The system includes a server that manages and stores this biometric data, which is associated with user IDs. The stored data consists only of graphical representations (e.g., waveforms or shapes) of the biometric information, not raw data. When a user requests deletion of their stored biometric data, the server removes the existing data linked to their ID and begins accumulating new biometric information transmitted under that ID. This ensures that only the most recent biometric data is retained, enhancing security and privacy by preventing unauthorized access to historical data. The system dynamically updates biometric profiles, allowing for continuous authentication without retaining outdated or unnecessary information. This approach improves flexibility and user control over biometric data storage.
4. The variable biometric information-based authentication system of claim 1 , wherein, when the specific ID is the ID of the first security level, the mobile terminal is configured to collect and store the variable biometric information in the unit of a predetermined time, and to add information regarding time to the variable biometric information and to store the information, and wherein the mobile terminal is configured to transmit the information regarding the time and the information regarding the figure or the form of the graph indicating the variation in the specific section, without transmitting the real value of the collected variable biometric information to the variable biometric information management server.
A biometric authentication system uses variable biometric data, such as heart rate or gait patterns, to verify user identity. The system addresses security risks by dynamically analyzing biometric variations over time rather than relying on static biometric data. For users assigned to a first security level, a mobile terminal collects and stores variable biometric information at predetermined intervals, attaching timestamp data to each recorded sample. The system then processes this data to generate a graph or figure representing biometric variations in a specific section, but instead of transmitting raw biometric values, it sends only the time-related information and the graph or figure to a central management server. This approach enhances security by preventing exposure of sensitive raw biometric data while still enabling authentication based on dynamic biometric patterns. The system ensures continuous monitoring and adaptive authentication by analyzing temporal changes in biometric signals, reducing the risk of spoofing or unauthorized access. The mobile terminal handles local data processing, minimizing the transmission of sensitive information to external servers.
5. The variable biometric information-based authentication system of claim 4 , wherein, when the login command regarding the ID is requested, the variable biometric information management server is configured to compare information regarding time, added to variable biometric information received from the mobile terminal, and the information regarding the time, added to the variable biometric information received from the variable biometric information management server, and to determine equivalence therebetween, and, when it is determined the respective pieces of information regarding the times are equal to each other, the variable biometric information management server is configured to determine equivalence between the respective pieces of variable biometric information, and to verify the validity of the login command regarding the ID.
This invention relates to a biometric authentication system that uses variable biometric information, such as behavioral or physiological data that changes over time, for secure user verification. The system addresses the limitations of static biometric authentication methods, which can be vulnerable to replay attacks or spoofing, by incorporating dynamic biometric data that is time-sensitive. The system includes a mobile terminal and a variable biometric information management server. The mobile terminal captures variable biometric information from a user, such as typing patterns, gait analysis, or voice dynamics, and appends time data to this information before transmitting it to the server. The server stores reference biometric data for registered users, also with associated time information. When a login request is made, the server compares the time data from the mobile terminal with the time data stored in its database. If the time data matches, the server then compares the variable biometric information itself to verify its authenticity. Only if both the time and biometric data match does the server validate the login request, ensuring that the authentication process is both secure and resistant to replay attacks. This approach enhances security by ensuring that biometric data is not only unique to the user but also time-bound, preventing unauthorized access even if biometric data is intercepted.
6. The variable biometric information-based authentication system of claim 1 , wherein, when the specific ID is the ID of the second security level, the mobile terminal is configured to collect the two or more types of variable biometric information, and to match respective pieces of classification information with the information regarding the ID, such that the respective types of variable biometric information are identified.
This invention relates to a biometric authentication system that uses variable biometric information to enhance security. The system addresses the need for stronger authentication methods beyond static credentials like passwords or fingerprints, which can be compromised. The system dynamically collects and processes multiple types of variable biometric data, such as gait, typing patterns, or behavioral traits, to verify user identity. The system assigns different security levels to user IDs, with higher levels requiring more stringent authentication. For a second security level, the system collects two or more types of variable biometric information from a mobile terminal. Each type of biometric data is classified and matched with the user's ID to ensure accurate identification. This multi-factor approach reduces the risk of unauthorized access by requiring multiple dynamic biometric inputs, making it harder for attackers to replicate or bypass authentication. The mobile terminal processes the collected biometric data in real-time, comparing it against stored profiles to confirm the user's identity. By using variable biometric traits, the system adapts to natural variations in user behavior, improving accuracy and security. This method is particularly useful for high-security applications where traditional authentication methods are insufficient. The system ensures that only authorized users with the correct biometric profiles can access sensitive data or services.
7. The variable biometric information-based authentication system of claim 6 , wherein, when the specific ID is the ID of the second security level, the variable biometric information management server is configured to receive, from the mobile terminal, first variable biometric information and second variable biometric information in which different types of classification information are matched with the information regarding the ID, and to store the first and second variable biometric information, and wherein, when the login command regarding the ID is requested, the variable biometric information management server is configured to receive first variable biometric information and second variable biometric information matched with information regarding the ID requesting the login command from the mobile terminal, and to individually determine whether the stored first variable biometric information and second variable biometric information are equal to the received first variable biometric information and second variable biometric information, and to verify the validity of the login command regarding the ID.
A biometric authentication system uses variable biometric data to enhance security for user login processes. The system operates within a multi-level security framework, where different security levels require distinct authentication methods. For a second security level, the system receives and stores two types of variable biometric information from a mobile terminal, each associated with a user ID. The biometric data includes classification information that distinguishes the different types of biometric inputs. During login, the system receives the same two types of biometric data from the mobile terminal and compares them against the stored data. The system verifies the login request only if both sets of biometric data match the stored versions. This dual-factor biometric verification ensures higher security for sensitive access levels, reducing the risk of unauthorized access. The system dynamically manages biometric data, allowing for flexible and secure authentication processes based on the security level assigned to each user ID.
8. The variable biometric information-based authentication system of claim 1 , wherein, when the mobile terminal is connected to a short range communication network, the mobile terminal is configured to transmit the stored variable biometric information to the variable biometric information management server at predetermined time intervals.
A biometric authentication system uses variable biometric information, such as dynamic patterns or behaviors, to verify user identity. The system includes a mobile terminal that captures and stores this variable biometric data, which changes over time to enhance security. The mobile terminal connects to a short-range communication network, such as Bluetooth or Wi-Fi, and periodically transmits the stored variable biometric information to a central management server at predefined intervals. This ensures the server has up-to-date biometric data for authentication purposes. The system may also include a biometric information registration device to initially enroll the user's variable biometric traits. The mobile terminal processes the biometric data locally before transmission, ensuring efficiency and reducing network load. The periodic updates help maintain accurate and current biometric profiles, improving authentication reliability. This approach addresses security risks associated with static biometric data by leveraging dynamic, time-sensitive information. The system is designed for environments where continuous or frequent authentication is required, such as secure access control or financial transactions.
9. The variable biometric information-based authentication system of claim 1 , wherein the variable biometric information comprises one or more pieces of information from among user's weight, body fat percentage, blood pressure, temperature, breathing rate, heart rate, blood glucose, muscle mass, total body water, protein, abdominal visceral fat, skeletal muscle mass, basal metabolic rate, exercise, number of steps, sleeping pattern, weight load pattern of both feet, and paces.
A biometric authentication system uses variable biometric information to verify user identity. The system addresses the limitations of static biometric authentication methods, which can be compromised by spoofing or changes in physical characteristics over time. By analyzing dynamic biometric data, the system enhances security and adaptability. The system collects and processes one or more variable biometric measurements, including weight, body fat percentage, blood pressure, temperature, breathing rate, heart rate, blood glucose levels, muscle mass, total body water, protein levels, abdominal visceral fat, skeletal muscle mass, basal metabolic rate, exercise patterns, step count, sleeping patterns, weight distribution between feet, and gait analysis (paces). These measurements are continuously or periodically monitored to establish a unique biometric profile for each user. The authentication process involves comparing real-time biometric data against the stored profile. Deviations beyond predefined thresholds trigger additional security measures or deny access. This approach improves fraud detection and accommodates natural variations in biometric data over time. The system can be integrated into wearable devices, medical monitoring systems, or access control mechanisms, ensuring robust and adaptive authentication.
